Every second counts, especially when it comes to fitting fitness into your super-busy life. But what can you do in a single minute? A lot—and these workout ideas are proof! Try squeezing them in one at a time throughout the day when things are really hectic, or mix and match a few when you have more time. The possibilities are endless.

How it works: For each circuit, do as many reps as possible of each exercise with proper form in the time specified. For a longer workout, choose three to five circuits and perform up to five rounds of your routine, or pick one circuit and repeat it five times, resting 30 to 60 seconds between circuits.

You’ll need: Some circuits require a set of 3- to 15-pound dumbbells.
